and it consists in a novel combination, with a pendentmotor, and a drillingtool attached thereto, of a supporting-frame, a; traveling carriage for shifting the position of the motor and---drilling-tool, and which is provided with guide-pulleys, and a supporting-chain or cable passing over said gnidepulieysi and having themotor suspended from the po 'tion of the chain or cable pendent between said pulleys, while the ends of said chain or cable are held fast, the said chain or cable forming the only connection between said motor and its frame and carriage, whereby provision is afforded for the movement of the frame without liability of breaking or straining the tool.

The invention also consists in the combination,withthe foregoing motor, tool, carriage,

and chains! cable, of a traveling frame sulpporting the, aforesaid traveling carriage, and

carrying a winch to which one end of the sup.

p'ozfc-ing chain or cable is attached, whei Jby provisimi is alforded for shifting the franio with the carriage upon it, or for shifting the carriage alone, and for raising or lowering the p drilling-tool and motor.

The invention also consists in the combination, with a double ponton, of a traveling frame extending between and movable length wise of thetwo portions of the ,ponton, one or more motors sns ended f om said frame, and one or more dril ing-t'ools attached to and- ?dapted to be.. operated by said motor or moors.

Inapplying the invention to snbai neons boring operations to which it is speoiallyadapted,'a double vessel or ponton is provided, the two halves thereof beingr'plaiced at a conve,

nient distance apart and firmly fixed together by means of ties or girders. On these pontons we provide a traveling or movable frame fitted with a platform and spanning the space between the two pontons. This frame serves to carry the lifting-gear and the motors for driving the boring-tools. The frame is so arranged that after the necessary number of the ponton's it can be moved to theposition required for the next or any other set of holes without shifting the pontons, thereby insuring perfect accuracy in boring the holes at the required distance from each other. The waterway between the pontons is preferably bridged across by loose planking, a single plank being taken up wherever required to allow the boring-tool to pass freely. The difference in the level of the pontons caused by moving the holes is bored along the required line between frame may be adjusted by the filling or emptying of water-tightcompartments in the pontons, asreqnired;

In the accompanying drawings, Figure l is a front elevation of our improved rockboring apparatus adapted to a; ponton. Fig. 2 is a I-side elevation of the same. view, showing the mode of binning together Fig. 3' is a plan the double vesseh Fig. djillustrates, on a larger scalethe manner of connecting theboring-tool with the shaft of the motor. Fig. 5 illustrates a system of gearing which may be employed to vary the speed of the boring. tool, and Fig. 6 is a sectional detail view of the lower portion of the boring-tool.

Similar letters of reference designatecorre I spending parts in the. several figures.

The double vessel which We employ is con strncted-wiih parallel sides, and is furnished with-a pair of rails, A A, laid parallelto each othermnear the inner sides of the ponton. I r

These rails A serve as a railway for the travcling or movable frame '3 which is fitted with a reticulated platform, B, and rises several feet above the platform, to-oarry rails 13 for the vre%p}tion of wheel-carriages C C. The

water-way betweenthe pontons is preferably bridged over by'loose planking, 'one'or more planks beneath the. traveling flame B being taken up as required,to allow the boxing-tools so 1 box, I, provided with glands for, endering the same water-tight. This water'rbox is supplied 2 assess 5' one for each boring-tool. In these carriages Q are mounted chain or uide pulleys 0, around which are laid chains made fast atone end to the top of the frame B, and let down to winches I), mounted on the platform B of the to frame Bf These chains d severally carry,at-

their portions which arepcndcnt between the guide-pulleys-c c, pulley-blocks E, from which depend chains 0 for carrying the motor-engines F for driving and weighting the boringtools. These motor-engines may be of any approved construction, and driven by steam, gas, air, or electricity. In Figs. 1, 2, and 3; we have indicated the employment of a Brotherhood steam-engine for this purpose, and. at Fig. 4we have shown on an enlarged scale the mode of fitting the aboringptool to theshaftof the engine, the object being not only to apply the direct action of the engine to the tool, but also'to use the weight of the engine for holding down the tool toitswork. I

' G is the boring-tool, the hollow stem of g which is formed in lengths, which are screwed -togcther, and are capable of being readily attached and detached, for the purpose of varymg the length of the boring-tool in the well- I known manner to adapt it to its work. Made fast to the lower end of the shait f of the .motor-engine is a sleeve, f, threaded internally, -120 receive a screw-coupling piece, f. The lower end of this screw-coupling piece enters a tapped socket in a'socket-ca ting, H, which is slotted transversely to receive a key, h. g The uppermost joint or portion of the boring- 4 0 tool is made solid at its topend, and shaped 1 t0 fit a socket in the socket-piece'H. This top end is also slotted to receive the key h which, when passed through it, secures the tool to the motor-engine. Immediatelybelow the solid part of this uppe'rmost joint of the horing'tool, and at thecommencement of the hollow portion thereof, the metal, is thickened to allow of its being pierced radially without against which fit the endsofian an larwaterby apipe, 1', with water under pressure from asteain-pump, K, and it is intended to de' liver a stream of water to the boring-tool, so as todrive out the borings from the bored hole. In some instances, in order to guide the tool in its work, we first, before applying the tool, inscrtinto the rock a guide-tube, such as that shown at L 11 L, Figs. 1 and 2. This tube we furnish, like theboring-tool,.with a ring of diamond-cutters, and operate it by hand, or otherwise, so as to make it take a 1 firm holdin the rock, its position therein being respond exactly to the position intended for v the hole which thehoringtoolisinfin'm. This 'weakening the part, and .to form shoulders tubes screwed together and fitted with a ring tube is withdrawnsuch as in jointy strata or determined by the operator, that it may cor-.

guide-tube is built up 'of suitable lengths, in the same way as the boring-tool, and to any desired height, and it thus serves as a guide for the tool whilethe tool is enteringthe rock, and afterward serves to'steady. it while the boring is proceeding.

0n starting to workjthe attendants slackcn the chains dfby unwinding thewinclics, and '75' thereby-allow the suspended motor-engincsio press their tools into work. As this work proceeds, the attendants continue siowly to lower the engines, and cause them to press. down thetools while iinpartin g rotary motion thereto", For the purpose of driving the en gines F, steam-supply pipes m, leading from. a boiler, M, are connected with the steamchamb'ersof the several engines; These pi pcs are. made 1 flexible, in order to allow for the 8 vertical movement of the engines. When an engine, has followed down. it's tool to a given distance, the tool-stem must be detached therefrom and lengthened by the insertion ofanother joint-piece, the engine being raised for that purpose, and the operation may then proceed as befor'e.

' Fig. 5 shows an arrangement of gearing which may be used for reducing the speedinr parted to thcboring-tool by the motive-power 9 engine. In this figure a dynamo-electric machine is represented as employed for working thetool. ()ntheshaft f of the engine iskeycd a spunpinion', 1, which gears into a spur-wheel,

2, on the axle of which-is keyed a pinion, 3. This pinion gears into a wheel, 4,-keyed ona short shait, 5, which is screwed to the socketpiece H of the boring-tool. These gear-wheels, which may be of any desired proportions, are inclosed in a box, N, made fast to the. motorengine, and constituting a coupling-piece for the engine and boring-tool. In this eascthc sleeve f and the screw-coupling piece f are removed, the coupling-piece or gear-box N temporarily taking their place. By thus in- IIO ter-posing the gear-box between the motor and the boring-tool the motor may still be driven at a high speed, even thoughcircumstances should necessitate the driving of the tool at a comparatively slow speed.

' Fig.6 shows in section the lower end of the boring tool which we prefer to employ, it being surrounded by a guide-tube, a above explained. The 1200] consists of a number of sh ort of diamond-cutters, thus leaving open the center of the tool for the discharge of water into thebored'hole. V

In cases where there is impossibility of the hole filling 'up again with silt after the boring- 'where hard and soft parts occur alter-rudelywe bore the hole to the required depth with a hollow tool sui'iiciently large to allow oi the explosive nnitcrial being passed down through" the tube tothebottom ol'theholc. Tllll"-.\\'ll(ll the tool 'is withdrawn, the explosive will be left in its proper position ready for firing.
